IRA BRONSON, OF LOCKPORT, NEV YORK.

BOB-SLEIGH.

SPECIFICATION forming part of Letters Patent No. 327,227, dated September 29, 1885.

Application med March 1e, 1884. (No model.)

To @ZZ whom it may concern.-

Be it known that I, IRA BRoNsoN, of Lockport, in the county of Niagara and State of New York, have invented :newr and useful Improvements in Bob-Sleighs, of which the following is a specification.

This invention relates to an improvement in that class of bob-sleighs which are adapted to be secured to the runninggear of an ordinary carriage or other vehicle, in the place of the Wheels which have previously been removed therefrom, and whereby a carriage or other wheeled vehicle can be readily converted into a sleigh.

The object of my invention is the production of an inexpensive and durable sleigh of this character, and it consists of the improvements which will be hereinafter described, and pointed out in the claim.

In thel accompanying drawings, Figure l is a side elevation of a carriage body mounted upon a pair of sleigh`bobs embodying my^invention. Fig. 2 is a perspective view of one of the sleigh-bobs. Fig. 3 is a vertical crosssection on line x x, Fig. l, on an enlarged scale. Fig. 4 is a fragmentary top plan view of one ofthe runners and connecting parts on an enlarged scale. Fig. 5 is a cross section `in line y y, Fig. 3.

Like letters ot' reference denote like part-s in the several figures.

A represents the carriagebody, and B B the front and rear axles.

C represents the front sleigh bob, and C the rear bob, supporting, respectively, the front and rear axles, B B. The bobs C C' each consist of a pair of runners, c c, provided with standards or knees c2, which support the upper part of each runner-frame. The standards c2 are preferably made of Wrought or malleable iron, and secured at their lower ends to the runners c and at their upper ends to a cross-piece or bolster, D. The bolster D extends on either side beyond the runners, and is preferably made of about the same length as an ordinary wagon or carriage axle.

E is a curved rod or iender,which connects the ends of the bolster D to the upper front portions of the runners c c, and which is secured at its ends by suitable bolts. f is a cross-rod connecting the front portions of the runners c c of each bob.

The cross-pieces or bolsters D are provided on their ends with boxes or bearings d, adapted to receive the spindles or journals of the axles of the carriage or wagon. These boxes d are constructed of wood or iron, as preferred, and are made with a tlat bottom surface, so that they will fit down tightly upon the holsters D. These boxes are made of such length and so arranged on thebolster D that the threaded ends of the axle-spindles project beyond the boxes and permit of the adjustment of the nuts upon such threaded portions to retain the axles in position upon the bobs and prevent any sidewise movement. The boxes d are secured to the cross pieces or" bolsters D by clips e, which pass over the boxes d and the holsters D.

Vhen it is desired to place a carriage or Wagon upon the runners, the clip e, which secures the box d to the bolster D on one side of the bob, is loosened and the box d removed from the bolster. up, the wheels are removed, and the bobs applied to the axles by slipping t-he box which is secured to the bob on onejournal, then applying the detached box to the other journal ofthe same axle, and finally securing this box to the bolster D by the clip c. The nuts being then applied to the threaded ends of the axle-spindles the bobs are firmly attached to the axles of the carriage or wagon.

The pair of runners of each bob are rigidly connected by the bolster D and rod f, Whereby bot-l1 sides of the vehicle are kept at the same level in passing over uneven surfaces, and the pitching incident to use of four separate or disconnected runners is avoided.

It is obvious that the boxes d may be rigidly secured to the bolster and constructed with removable caps for the insertion and removal ot' the axle-spindles.

I claim as my inventionk The carriage is then lifted In a removable sleigh-bob, the combination 9 5 of the runners c c, standards c2, fender E, cross-bar f, and bolster D, and boxes d, removably secured to the bolster D by clips e, substantially as set forth.

Witness my hand this 13th day of March, 1884.
